Lochinvar & A.O. Smith 100208556 Flue Temperature Sensor Kit

The Lochinvar & A.O. Smith 100208556 Limit Flue Sensor Kit is an essential safety device found in combination gas boilers and gas furnaces. This device keeps a check on the flue gas temperature and avoids going beyond the threshold limit. Such restrictions are vital to ensure safety from carbon monoxide buildup and other operational hazards that could lead to damage to the equipment. The kit includes a temperature probe and a control unit. The probe is fitted inside the flue duct where it obtains the temperature of the flue gas. If the temperature in the probe exceeds a preset temperature range, the control module activates a safety shutdown sequence which usually entails switching off the burner to avert any further problems.
